I am moving this week from my apartment and reading this book "The Design of Everyday Things" made me have a new look to the things i have and the way i should organize them. Simply thinking of their affordances and constraints made me easily get ride of a lot of stuff or reconstruct other to fit in my new place. For a long time, as a user of Things, i was talking things for granted and give the designer high credits and never thought that things might have bad designs. Believing that things have been tested for usability, dropped me in the cave of blaming myself for not being smart enough to intuitively use them.
There is a critical need for a universal design standards that make it easy for most people to use things intuitively. Even when i studied programing and design, have seen many designers design their things the same way they used to use them regardless of the bad design it might have. I believe now that designers have to first, through away all their previous perceptions about what they design and think about its conceptual design as if it's a new invention, then consider their constraints and resources.
